accessing elastix server from 2nd ip range

I have just installed Elastix for a business environment with a vpn setup that consists of two different ip ranges for two separate offices (192.168.1.x and 192.168.2.x)

The Elastix server is sitting on the 192.168.1.x range with all extensions on with an ip in this range being able to connect fine. I am having the problem connecting extensions that have an ip address on the 192.168.2.x range.

I can communicate from 192.168.2.x fine to any PC on the 192.168.1.x range EXCEPT to the Elastix server.

Would I have to add a static route for the 192.168.2.x range on the elastix server?
